Title: A device for changing the method of operation of a time-delay electric relay
IPC: H01H43/28
Filed: 1963-08-13
Abstract: 1,012,544. Electromagnetic relays. TELEMECANIQUE ELECTRIQUE. Aug. 13, 1963 [Aug. 28, 1962], No. 31967/63. Heading H2B. A switch is operated after a preset delay alternatively following the energization or deenergization of an electromagnet, this change of function being obtained by the mere rotation of a screw. An actuating unit 2, comprising an electromagnetically - operated plunger 4, and a time-delay contact unit 3 are mounted on a base plate 1 which also carries a rocker arm 6 interconnecting the plunger 4 and a tappet 5A engaging the operating member 5 of the unit 3. The member 5 is capable of returning elastically and slowly to its initial position after having been depressed. As shown, the arm 6 is free to pivot on a shaft 7 which is threadedly engaged at one end in a support 8 and at the other end has a conical part 7C seating in a V-notch 15. Under these conditions energization of unit 2 causes plunger 4 to rock the arm 6 such that member 5 of unit 3 is depressed; upon subsequent de-energization of unit 2, unit 3 will restore with a delayed action. The shaft 7, however, may be screwed into support 8 by means of a slotted head (Fig. 3, not shown) whereupon projections 12A, 12B on arm 6 enter apertures 13A,13B in support 8 and lock the arm and support together. This prevents arm 6 pivoting about shaft 7 but the withdrawal of cone 7C from notch 15 allows support 8 to pivot about an axis X-X 1 , under the action of a spring 14, since it is journalled at 9A 10A and 9B, 10B. Spring 14 thus urges arm 6 towards the units 2 and 3 and holds member 5 depressed. Under these conditions energization of unit 2 causes plunger 4 to pivot the assembly of arm 6 and support 8, releasing member 5 which after the pre-set delay returns to the unoperated position. The delay unit 3 may comprise a pneumatic or clockwork mechanism.

Title: Recovery of solvents from mixtures containing them by multi-stage evaporation
IPC: B01D1/26
Filed: 1954-11-04
Abstract: In a process of solvent-recovery from a mixture of a liquid product and a solvent of lower boiling-point than the liquid product wherein the solvent is evaporated from the mixture in a plurality of stages operated at progressively decreasing pressures and at increasing temperatures from at least one stage to the next following stage, the solvent-containing liquid product withdrawn from a lower temperature stage is heated, prior to being introduced into the subsequent stage, by mixing it with part of the solvent-free liquid product withdrawn from the last stage, said part of the liquid-product having been heated after leaving the last stage, and the quantity and temperature of the heated liquidproduct being adjusted so as to expel the solvent from the mixture in said subsequent stage.  The process, which avoids harmful decomposition <PICT:0800424/III/1> reactions at high temperatures, may be applied to the raffinate obtained by treating a hydrocarbon oil with liquid sulphur dioxide.  Raffinate containing 5 parts (by weight) of oil and 2 parts of SO2 is fed through conduit 1 to heatexchanger 2 where it is heated to about 180 DEG  C., and some of the solvent evaporates.  The mixture enters evaporator 3 where about 1.9 parts of gaseous SO2 are separated under a pressure of 6 atm. abs.  The SO2-vapour passes through conduit 30 to condenser 31. The raffinate solution, withdrawn from evaporator 3, is mixed in conduit 4 with 1.4 parts of SO2-free raffinate at 280 DEG  C. introduced through conduit 13; and the mixture, which is at about 200 DEG  C., is introduced into evaporator 5 where the bulk of the residual SO2 in the raffinate is vaporized at a pressure of 1 atm. The raffinate withdrawn from evaporator 5 is introduced into evaporator 7 where a pressure of 0.05 atm. is maintained by pump 39 and the last traces of SO2 are expelled from the raffinate.  The SO2-free oil is pumped from evaporator 7 through tubular heater 11 where it is heated to about 280 DEG  C.  Part of this heated oil is passed through conduit 13 for admixture with raffinate from evaporator 3; and another part is passed through conduit 14 into heat-exchanger 2. Heat-exchangers 17, 18 and 21, and evaporators 19, 22 and 24, are employed for separating SO2 from the extract.  The SO2-free extract is pumped from vacuum-evaporator 24 to heat-exchanger 17, and is then withdrawn via conduit 27 to storage. Heat-exchangers 21 and 18 are heated by some of the SO2-free raffinate from conduit 12.  The cooled raffinate leaves heat-exchanger 18 through conduit 12c, in which it is united with the raffinate from heatexchanger 2; the united raffinate is then withdrawn to storage.  When solvent is evaporated from low-boiling oil fractions, part of the oil is vaporized with the solvent.  In such cases provision is made for the reflux-return to evaporators 5, 7, 22 and 24.  Chlorinated hydrocarbon solvents are referred to.
